"I met him, and like, cried," she added. "It was really weird. It was so weird. It was so uncharacteristic of me. I'm usually sort of chill. I'm usually somewhat contained, but I met him and [makes crying face]."

And she wasn't exaggerating. Grande actually Instagrammed a video of when she first met Carrey in April, and sure enough, the tears flowed when he gave her a hug.

Grande stressed that Carrey was just as great in person as she imagined he would be.

"I was kind of nervous to meet him, because, I was like, you know, he's been my crush forever. What if he's not as nice as I'm expecting?" she explained to Ripa and Strahan. "He was so over-the-top nice, and perfect, and just as I hoped he'd be. [He said to me in] his classic Jim Carrey, 'Nice to meet ya. Thank you. Remember, be nice.' I was like, 'Oh my God, you're so cute. I love you.' I was like, 'Wow, help me God, thank you.'"

This isn't the first time the Scream Queens star has made her love for the Dumb and Dumber To actor known. Earlier this month, ETonline exclusively debuted the first installment of Between 2 Queens -- a killer new talk show featuring the stars of Fox's Scream Queens -- in which she dished to her co-star Emma Roberts that Carrey was her "first" crush.

Sadly, the actor is currently mourning the death of his girlfriend, 30-year-old Cathriona White, who was found dead in her Sherman Oaks, California residence from an apparent suicide on Monday. Assistant Chief Coroner Ed Winter tells ET that there were pills located next to White when her body was found, and a note was also retrieved at the scene that included Carrey's name. The two had been dating on and off since 2012.

"I am shocked and deeply saddened by the passing of my sweet Cathriona," Carrey said in a statement to ET on Tuesday. "She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled. My heart goes out to her family and friends and to everyone who loved and cared about her. We have all been hit with a lightning bolt."
